Title: Soot collecting apparatus
Inventor: OTA AKIRA
IPC: B03C3/16
Filed: 1989-01-23
Abstract: PURPOSE:To permit an efficient collection of even fine soot particles by providing a spray mechanism for shooting out an adsorbing solution and an oppositely positioned electrode and applying to the adsorbing solution a high voltage of the charge opposite to that of the soot particles. CONSTITUTION:A charging part 22 applies a high voltage to soot 25 drawn in a case 1 to charge the soot particles 25a with static electricity. A high voltage of the charge opposite to that of the soot particles 25a is applied to an adsorbing solution 14 consisting of water or in mixture with surfactant and this adsorbing solution is supplied into the case 1. Also, a spray mechanism 8 shoots out fine liquid particles 14a of the adsorbing solution 14 against the passage of the soot 25. The fine liquid particles 14 travel to an electrode 15 provided oppositely to this spray mechanism 8 by its attractive force. As a result, the fine liquid particles impinge against the soot particles and, under the forces of inertia and static electricity, adsorb the soot particles and thus the waste liquid results, permitting an efficient collection of even fine soot particles.

Filed: 1988-01-25
Abstract: PURPOSE:To correctly judge the generation of hesitation of an engine in quantitative ways by installing a judging means which judges the generation of hesitation when the sampling value of the car speed signals of a vehicle becomes over a negative certain value. CONSTITUTION:A car speed signal is supplied from an input terminal 1. A boost signal is supplied from an input terminal 5.

The hold value is inputted into a differential amplifier 2, together with the car speed in that period, and the difference value is outputted. Though the output is a positive value in the normal acceleration state, if a hesitation is generated, the output is a negative value. Therefore, the generation of hesitation of an engine can be correctly judged in quantitative ways.

Abstract: PURPOSE:To realize monitoring extending over a long period by generating an alarm by deciding the discordance of logical information based on comparison between the read voltage level of a memory cell and reference voltage or different reference voltage. CONSTITUTION:An outflow current CD0 from a corresponding ROM cell is converted into voltage Vc by a current detection circuit 21, and is compared with the reference voltage Vr1 from a reference voltage generation circuit 20 by a first comparison circuit 24, and the logical information corresponding to the storage contents of the ROM cell is outputted. Similarly to this logical information, coincidence or discordance with the logical information based on the reference voltage Vr2 higher than the voltage Vr1 a second reference voltage generation circuit 22 outputs through a second comparator 25 is decided, and at the time of the discordance, alarming H output is generated from a decision circuit 27. Thus, a warning is issued for a fact that the negative potential threshold of an erasure state becomes higher because of the deterioration of an element due to the preservation of the long period and a read current becomes less, and the quality of the erasure state is monitored. Similarly, the deterioration of a write state is monitored on the basis of the reference voltage Vr3 lower than the voltage Vr1.
